The instrument is used to measure Gel Time using two measuring methods based on DIN EN ISO 2535. When method 3 is selected the curing process can be monitored whilst the test stress is built up, which can be done either continuously or in a series of pulses – as on the earlier GELNORM Model RVN. Using the provision for continuous monitoring of the temperature, the point in the cycle when the maximum temperature is reached in the specimen can be established. The temperature monitor built into the PVN-1 can be used to control the heating equipment for the specimen. Description The instrument is used to measure the time required for a defined formula material (resin, accelerator, initiator), to reach a viscosity of 50 Pa*s under defined conditions. A rod made of glass, delrin or alumin- ium, immersed to a defined depth is rotated in the specimen. The procedure is provided with an automatic release device for the specimen, which is held in a beaker or in a test tube. The system can be used employing any one of 3 measuring methods. Method 1: with test tube Method 2: with beaker Method 3: with test tube, or beaker for rotating either continuously - or pulsating. The method 3 is provided for the users of the Gelnorm RVN (previous device). It is recom- mended to make an initial trial measurement when a new mixture is to be tested, in order to establish the characteristics of the mixture. The GELNORM ® – Geltimer PVN-1 consists of: ▪ The Control unit (with connections for the measurement of the specimen temperature, the motor on which the rotating test rod is mounted, and a connection for electric heating, is an option) ▪ The Stand with movable mounting for the motor ▪ The motor with test rod holders The control unit for the PVN-1 has a USB port and is delivered with Windows software based on the “dot net“ system. The software can be copied easily and no installation is necessary beyond this. It requires only an EXE File running with INI data. The system and the measurement can be configured directly on the PC. The recorded data are displayed graphically and can be processed as a csv-file in other programs. The device can be used in online mode only!
